Since you replaced all the javascript folder, ensure the folder permissions are recursively set to 0755 on your file server and that those files being re-uploaded through your host file manager console, not over FTP.

The most generated errors being found on Opencart forum originates from contributed programming. The increased post counters are caused by redundancies of the same solutions that were already provided prior.

thanks found the problem now.

If there are files bigger than 3mb the image manger won't load. I have removed the images now once again I uploaded a 4MB test file the manger won't popup again.

How can fix it for good.
1- warn user of uploaded file size.

thanks

Since these topics begins to evolve more and more, an interesting concept I discovered on: https://stackoverflow.com/questions/130 ... pload-size is the validation of the file size and useful for each servers.

Let's integrate this idea. In admin/controller/tool/upload.php file,

find:

Code: Select all

public function upload() {

add above:

Code: Select all

protected function validateSize() {
		$max_size = -1;

		$files = array_merge(array(php_ini_loaded_file()), explode(",\n", php_ini_scanned_files()));

		foreach (array_filter($files) as $file) {
			$ini = parse_ini_file($file);
		  
			$regex = '/^([0-9]+)([bkmgtpezy])$/i';
		  
			if (!empty($ini['post_max_size']) && preg_match($regex, $ini['post_max_size'], $match)) {
				$post_max_size = round($match[1] * pow(1024, stripos('bkmgtpezy', strtolower($match[2]))));
			
				if ($post_max_size > 0) {
					$max_size = $post_max_size;
				}
			}
		  
			if (!empty($ini['upload_max_filesize']) && preg_match($regex, $ini['upload_max_filesize'], $match)) {
				$upload_max_filesize = round($match[1] * pow(1024, stripos('bkmgtpezy', strtolower($match[2]))));
			
				if ($upload_max_filesize > 0 && ($max_size <= 0 || $max_size > $upload_max_filesize)) {
					$max_size = $upload_max_filesize;
				}
			}
		}

		return (int)$max_size;
	}

Then, find:

Code: Select all

if ((utf8_strlen($filename) < 3) || (utf8_strlen($filename) > 128)) {

add above:

Code: Select all

$size = getimagesize($filename);

$max_size = $this->validateSize();
				
				if ($size && (int)$size > $max_size) {
					$json['error'] = $this->language->get('error_filesize');
				}

In catalog/controller/tool/upload.php file,

find:

Code: Select all

$this->response->addHeader('Content-Type: application/json');
		$this->response->setOutput(json_encode($json));
	}

add below:

Code: Select all

protected function validateSize() {
		$max_size = -1;

		$files = array_merge(array(php_ini_loaded_file()), explode(",\n", php_ini_scanned_files()));

		foreach (array_filter($files) as $file) {
			$ini = parse_ini_file($file);
		  
			$regex = '/^([0-9]+)([bkmgtpezy])$/i';
		  
			if (!empty($ini['post_max_size']) && preg_match($regex, $ini['post_max_size'], $match)) {
				$post_max_size = round($match[1] * pow(1024, stripos('bkmgtpezy', strtolower($match[2]))));
			
				if ($post_max_size > 0) {
					$max_size = $post_max_size;
				}
			}
		  
			if (!empty($ini['upload_max_filesize']) && preg_match($regex, $ini['upload_max_filesize'], $match)) {
				$upload_max_filesize = round($match[1] * pow(1024, stripos('bkmgtpezy', strtolower($match[2]))));
			
				if ($upload_max_filesize > 0 && ($max_size <= 0 || $max_size > $upload_max_filesize)) {
					$max_size = $upload_max_filesize;
				}
			}
		}

		return (int)$max_size;
	}

Then, find:

Code: Select all

if ((utf8_strlen($filename) < 3) || (utf8_strlen($filename) > 64)) {

add above:

Code: Select all

$size = getimagesize($filename);

$max_size = $this->validateSize();
				
				if ($size && (int)$size > $max_size) {
					$json['error'] = $this->language->get('error_filesize');
				}

Then, in your catalog/language/<your_language_code>/tool/upload.php file, at the bottom of the file, add:

Code: Select all

$_['error_filesize']   = 'Warning: Incorrect file size!';

If the key name error_filesize isn't there already. This should rectify the issue.

Post updated above. Take note that these modifications will only work if the basedir and safe-mode are NOT enabled.
